1.	Among the following , identify the species with an atom in +6 oxidaiton state of metalA. `MnO_(4)^(-)`B. `Cr(CN)_(6)^(3-)`C. `NiF_(6)^(2-)`D. `CrO_(2)CI_(2)`
Answer» Correct Answer - D oxidation of stte of Cr is +6 `(Cr_(2))O_(7))^(2-)+14H^(+)+6e^(-)rarr2Cr^(3+)+7H_(2)O` Equivalent mass of `K_(2)Cr_(2)O_(7)`=(Molecular)/(6)mass`
